JavaScript解决兼容性的函数以及兼容性方法列表

添加事件监听的封装兼容

function addEvent(Ele,Event,callback){
	if(Ele.addEventListener)
		Ele.addEventListener(Event,callback)
	else if(Ele.attachEvent)
		Ele.attachEvent("on"+Event,callback)
	else
		Ele["on"+Event]=callback;
}

删除事件监听的封装兼容

function removeEvent(Ele,Event,callback){
	if(Ele.removeEventListener)
		Ele.removeEventListener(Event,callback);
	else if(Ele.detachEvent)
		Ele.detachEvent("on"+Event,callback);
	else
		Ele["on"+Event] = null;
}

阻止事件的冒泡

function stopBubble(Event){
	if(Event.stopPropagation)
		Event.stopPropagation();
	else
		Event.cancelBubble = true;
}

阻止默认事件

function stopDefault(Event){
	if(Event.preventDefault)
		Event.preventDefault();
	else
		Event.returnValue = false;
	//return false;
}

默认样式的兼容

function getStyle(ele,attr)
    if(ele.currentStyle){
        return ele.currentStyle[attr];
    else
        return window.getComputedStyle(ele,false)[attr];
}

兼容性方法

var Event = Event || window.event;
var Event.target = Event.target || Event.srcElement;
var KeyCode = eve.KeyCode || event.which;
var scrollTop = document.documentElement.scrollTop || document.body.scrollTop;
